A robot for painting outdoor building walls based on parallel mechanism

Abstract

The invention relates to an outdoor building wall whitewashing robot based on a parallel mechanism. The robot comprises a fixed frame, six parallel branch chains are mounted on the fixed frame, and the upper ends of the six parallel branch chains are evenly mounted on an upper platform. Four lifting branch chains are symmetrically mounted on the upper end face of the upper platform. Each lifting branch chain comprises two mounting columns, wherein a first rotating shaft is mounted between the upper ends of the two mounting columns through bearings, a transmission pulley is mounted on the first rotating shaft through a key, a steel wire rope is attached to the inner wall of the transmission pulley in a sliding mode, and the top end of the steel wire rope is wound on a driving pulley. Each driving pulley is mounted on a second rotating shaft through a key, the two ends of each second rotating shaft are mounted on two lifting support plates through bearings correspondingly, and the lower ends of every two lifting support plates are welded to the upper platform. A lifting motor is mounted at the end, away from the corresponding mounting columns, of each second rotating shaft through a coupling. The outdoor building wall whitewashing robot has a stable-lifting automatic whitewashing function, and a new path of mechanical and automatic wall whitewashing is provided.

Description

technical field [0001] The invention relates to architectural decoration equipment, in particular to an outdoor building wall painting robot based on a parallel mechanism. Background technique [0002] With the rapid development of my country's national economy and the rapid pace of urbanization, the demand for real estate in China's social situation is increasing. From the perspective of safety, the state and local governments have issued laws and regulations, clearly stipulating that exterior wall coatings should replace The rigid requirements of exterior wall tiles increase the workload of exterior wall painting. At the same time, with the improvement of people's living standards, the frequency of house maintenance and redecoration is accelerating, and the wall painting market will still maintain a strong demand. The survey shows that the effect of wall decoration accounts for 80% of the overall decoration effect of the living room. That is to say, the quality of the inte...
